Application filed May 11,

This invention relates to improven'ients in the driving mechanisms of drums of various kinds, more particularly to devices of this character employed in leather manufacturers establishments, and has for one of its objects to simplify and improve the construction and increase the elliciency and utility of devices of this character.

Another object of the invention to provide a device of this character wherein the driving mechanism is applied direct to the drum, thus dispensing with all driver chains, belts, and the like, and materially decreases danger to persons employed in the vicinity of the drum.

With these and other objects in view the invention consists in certain novel features oi construction as hereinafter shown and described and then specifically pointed out in the claim, and in the drawings illustrative of the preferred embodiment of the invention:

Figure 1 is an end view of a conventional drum and the operating; mechanism applied.

Fig. 2 is an enlarged end View of the worm gear transmitting mechanism.

Fig. is a side view oi the parts shown in Fig. 2.

Fig. 1 is a detached plan view of the cap member of the worm pinion supporting bracket.

Fig. 5 is a detached plan view oi the base ll'li-ltllfiifiz' ot' the worm pinion supporting bracket,

The drum or like container which is to be rotated is indicated conveniently at and mounted for rotation in the usual manner on stub shafts, one of which is represented conventionally at 11.

Attached one end of the drum 10 as by screws 12, is a ring worm gear 13 of relatively large size.

Atta lied in any suitable manner to a vertical support, a part of which is indicated at 1a, is a lower bracket 15 having upwardly cpening half bearings 16 in spaced relation, and an upper bracket 17 suitably attached to a horizontal support a part of which is indicated at 18. The upper bracket is provided with opposing spaced halt bearings 19 coacting with the half bearings 16 of the lower bracket to support a shaft 20. The

confronting portions of are rigidly connected at portions at each side of shown.

The bracket members 15 and 17 when connected to the supports 14C and 18 and united by the clamp bolts form a very substantial and rigid support for the shaft 20 and the the two brackets their confronting the bearings, as

worm pinion 2-1 and independently of the drum 10 and its worm gear 13, so that the drum may be removed. and replaced. without disturbing the worm pinion and its operating m chanism, or the worm pinion and operating mechanism removed or replaced without disturbing the drum and its attachments.

The extended portion of the shaft 20 may be rotated by any suitable power, for iIistance by an. electric motor indicated conventituially at 23.

The improved device is simple in construction, can be manufactured of any desired size or capacity and is operated without the necessity for the employment of chains, belts or the like. The worm pinion and the worm wheel may be covered by a suitable hood to render them sate and prevent accidental contact with the attendants who are operating the drums.

The 'n-eit'erred embodiment of the invention is disclosed in the drawings and set forth in the specification, but it will be understood that modifications within the scope of the claimed invention may be made in the construction without departing from the principle of the invention or sacrificing any of its advantages, 1

Having thus described the invention what. is claimed as new is:

A device of the class described comprising a lower bracket adapted to be attached to a support and having spaced halt bearings, an upper bracket adapted to be attached to a support and having spaced halt bearings (reacting: with the half bearings ot the lower b ticket, and means for connecting the brackets at opposite sides of the half bearings.
